如何在代码中打开或关闭 SwitchCompat

Question

I want to turn a SwitchCompat widget on or off in code. I mean like when user changes a SwitchCompat from On to Off or otherwise. I want to do this in code. How would I do it?

SwitchCompat switchCompat = (SwitchCompat) findViewById(R.id.switch_compat);

Answer 1

As with any CompoundButton , you change the checked state of a SwitchCompat programmatically via setChecked() .

Answer 2

Programatically to change the state of a SwitchCompat control using setChecked() method.

SwitchCompat switchCompat = (SwitchCompat) findViewById(R.id.switch_compat);
switchCompat.setChecked(true); //checked.

or

 switchCompat.setChecked(false); //unchecked.

Or you can define the checked state directly inside the layout:

   <android.support.v7.widget.SwitchCompat
                android:id="@+id/myswitch"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"

                android:checked=true/>

Answer 3

It is also possible to use switchCompat.isChecked = false in Kotlin

Answer 4

You can use the setChecked(boolean state) method of the SwitchCompat.

Answer 5

Kotlin

bind.btSwitch.isChecked = true 

if using databinding or:

val btSwitch = findViewById<switchCompat>(R.id.specificID)
btSwitch.isChecked = true

accesing via findViewById
